Abstract

1440385 Bar stock feeding ASUMA SANGYO CO Ltd 14 June 1973 [20 June 1972] 28279/73 Heading B3B A feeder for feeding bar material to a multispindle machine tool comprises a plurality of feed tubes 210 arranged circumferentially on indexable tube holders 205 drivingly fixed to a central tube body 210 which is adapted to be indexably driven through a drive disc 204 by the multi-spindle head of the machine tool, each tube having a fixed portion and a pivotable cover portion which can be moved to allow a lateral feed of a bar into the tube, a chain driven push rod in each tube including means for laterally ejecting a piece of residual material through the side of the tube at a retracted position, a plurality of motors 460 to drive respectively each push rod, and an electrical contact plate 704 mounted adjacent an indexable disc 410 which carries a plurality of wiper contacts 448 that engage the contact plate 704 at predetermined indexed positions to start a respective motor 460. Bars are carried by support arms 114 and roll down to a rotary disc 315 having a cut-out 315<SP>1</SP> which carries one bar downwards to drop in into an open feed tube 210. The pivotable cover portion of each feed tube 210 has an arm 216 which engages an actuating arm 304. When a jack 309 is extended, arm 304 acts on the arm 216 to open the feed tube at the same time as linkage 305, 319, 316 rotates the disc 315 to release a new bar. Each feed tube contains a push rod (520) (Fig. 14, not shown) having a collet bar gripping portion (501) rotatably mounted on the remainder of the push rod. A concentrically arranged ejector rod (512) is actuated when the push rod is fully retracted by an end stop (514) striking an end closure of the feed tube 210. The push rod is moved by a chain (517) which passes through guide tubes 220, 221. The motors 460 each drive, through bevel gears, a chain drive sprocket 420. The feeder is mounted on roller 103 supports for movement along a track 104. Electrical control.-The motors 460 also drive, through a worm-wheel reduction (Fig. 18, not shown) a control member having striker arms that actuate switches to synchronize the stages of operation of the feeder, including a clutch control of the machine tool. The rear end of the central tube body 201 adjacent a bearing 202 carries a cam plate 260 and roller arm operated switch 264 and a ball locking detent, to locate the indexed position of the feeder. The said switch 264 prevents sparking of the contacts 448 upon contact with contact plate 704 by energizing the plate 704 after contact is made and de-energizing it before contact is broken.
